Digital Networks North America DNswitch 800 Configuring Bridge MIB Extensions, Bridge Capability

Parameter	Default	Description
FastForwarding	ENABLED	This parameter is used to enable/disabled the
		Fast Spanning Tree mode for the port. In this
		mode, ports skip the Blocked, Listening and
		Learning states and proceed straight to
		Forwarding.
		FastForwarding enables end-node workstations
		and servers to overcome time-out problems when
		the Spanning Tree Algorithm is implemented in a
		network. Therefore, FastForwarding should only
		be enabled for ports that are connected to an end-
		node device.

Configuring Bridge MIB Extensions

The Bridge MIB includes extensions for managed devices that support Traffic Classes, Multicast Filtering and Virtual LANs. To configure these extensions, use the Extended Bridge Configuration screen as shown below:

Bridge Capability

	Figure 3-18. Bridge Capability
Parameter	Description
Extended Multicast	Indicates that the switch does not support the filtering of
Filtering Services	individual multicast addresses based on GMRP (GARP
	Multicast Registration Protocol). Note that this function is not
	implemented in the current firmware release.
Traffic Classes	Indicates that the switch provides mapping of user priorities to
	multiple traffic classes. (Refer to the Priority menu on page 28.)
Static Entry	Indicates that the switch allows the static filtering of unicast and
Individual Port	multicast addresses. (Refer to the Address Table Configuration
	on page 19.)
Configurable	Indicates that the switch allows you to override the default PVID
PVID Tagging	setting (Port VLAN ID used in frame tags) and its egress status
	(VLAN-Tagged or Untagged) on each port. (Refer to VLAN Port
	Configuration on page 36.)
Local VLAN	This switch does not support multiple local bridges (that is,
Capable	multiple Spanning Trees).
